I can't pass CString or wstring to other project.

Hi, I've had sub-project.
When I made a method which has 2 or 3 CString or std::wstring parameters,
it can pass it without any problem.

But, when I tried to make that kind of method in other project,
(it's tied by Dependency and I've set Unicode, Multi-Thread Dll Debug. All
Project have same settings)
it makes that kind of link error.

ClassWizard error LNK2019: unresolved external symbol "public: class
ATL::CStringT<wchar_t,class StrTraitMFC_DLL<wchar_t,class
ATL::ChTraitsCRT<wchar_t> > > __thiscall
maymfc::CPathInfo::GetFolderPath(enum maymfc::CPathInfo::FolderType)"
(?GetFolderPath@CPathInfo@maymfc@@QAE?AV?$CStringT@_WV?$StrTraitMFC_DLL@_WV? $ChTraitsCRT@_W@ATL@@@@@ATL@@W4FolderTyp
e@12@@Z)
referenced in function "private: void __thiscall
CClassWizardDlg::InitTheme(void)" (?InitTheme@CClassWizardDlg@@AAEXXZ)

(I tried to call CPathInfo::GetFolderPath() ( it return CString. ) from
CClassWizardDlg class.
The class method looks weird but, it just pilot program, anyway. :) )

So, what is the problem?
Before I try to UNICODE, that kind of problem doesn't happen, I guess.

Thanks in advance.

Make sure your library is properly linked into this project.
